Fix broken ryfs_read routine, bump version to 0.3.1

Browse Source 
There were two issues here:
First, ryfs_read_sector_loop was not setting the current sector to the
next sector of the file being read. This had the effect of making it
read the same sector over and over again.
Second, the destination pointer for the `copy_memory_bytes` call wasn't
being changed after each sector copy.
